Dear Thin Film Experts,
I wish to know how to simulate light sources like Sun spectrum, xenon
lamp, incandescent lamp, etc. in Thin Film Software. This simulation
will help in designing filter coatings that modify the spectra of

Hi Friends,
Does anyone know a patent law firm that is well versed in optical matters?
Not necessarily lens design, but illumination systems, video cameras,
microscopes, that kind of thing.

I need to machine and polish simple reflector array for a row of LED
emitters from bar stock, but I don't know what alloy (or un alloyed) or
where to get the stock.

I'm currently looking to buy a transmitted light microscope to help me
in my studies of lichens and as a replacement for my old monocular
ex-university Meopta. Having read various discussions from the
archives of this newsgroup (which have generally been excellent and

I have been hearing about chinese glass and how cheap they are but I
would like to know more in order to include these in a design for cost
reduction.
I would like to know about:

I plan to buy a tunable laser (50 to 100 mW) at 780 nm to build a  Rb
MOT. The three main suppliers of commercial lasers that I know are
NewFocus, Toptica, and Sacher, and they made comparable offers. I'd
really like to know if one company have more robust and reliable

Am am interested in using an optical navigation sensor from Agilent in
mobile robotics.  Essentially I want to use the Agilent ADNS-3060 High
Performance Optical Mouse Sensor [1] more or less as designed.  I say
more or less because the original optical mouse design places the above

Just picked up a very old laserdisc player from a GM dealership.
It is the PR7820. Some of the mirrors for directing the beam are out
of wack. I have a very old set of directions on how to manualy adjust
these mirrors to get the correct beam path. Some of the steps require

Bit new to this, so apologies if it sounds a little confused.
I'm working with a sound artist to produce an interactive installation
that will eventually use a laser.
We're using a piece of software called Max/MSP which allows you to

Ok I picked up one of the LSI N2 modules that are getting dumped on
ebay. If you buy one of these, get ready to pay for shipping on 7
pounds of orange rubber HV potting. About the only thing useful if you
get one of these and its dead are 2 mirror mount assemblies that bolt

Does anyone know where I can find the latest revision of Scratch/Dig
Drawing C7641866?  It seems to exist cause folks in this topic
references it:

Slightly off topic, but if anybody knows, they're in this group...
Having never used one of these pieces of equipment, I wonder what this spec
means? We are faced with the task of matching the color of two different
pieces of plastic and the variariation can be no more than " 2 ...

I have placed 74 of my laser and optics collection on e-bay for anyone
who is interested. They are going for cheap. Check it out.
